Here's the bran-new performance e-bike from Qulbix, the 5th bike model for the 5th year anniversary:

Q140MD Core

Q140MD Core offers the best of both worlds – a powerful motor combined with the ability to pedal at high speed.
Bike's perfectly centralised mass makes the Q140MD an ultimate off-road e-bike, both power packed & nimble, offering the rider speed, torque and a hard-core workout.

Nice mid drive. Love the fact that you stick to your guns and deliver both e-bike version and moto version with foot pegs. Any chance you will go the extra mile getting your bike EU 45 km/h road legal? The idea of a hub motor as a mid drive I find very appealing, as these will be a silent mid drive just as we got the silent dd hub. Nice work. Got any riding video's?

I was excited to see your new mid drive this winter, however I've been waiting and waiting for more details. Checked both this thread and your website without much details.

I think this mid drive will make very much sense for the ES DIY crowd if the mid drive becomes a frame kit as well. As it stands right now it seems the price will be a big problem as there is an alternative mid drive from China at half your asking price, which people already seems smitten by. Really too bad Qulbix didn't bring the Q140MD Core to market last year as I think that would have been a whole other ball game for you, with the LMX and russian mid drive Vector sells as about the only competitor. This year it seems China got it locked down tight at a price point hardly any one can compete against with decent quality on both drive train and bike parts.

Your mid drive as a frame kit would make sense because lots of people got plenty of dd hub bikes and parts laying around they could put to good use in a Qulbix frame kit.

Btw any chance we will see a rear suspension linkage setup like ie the Sur Ron on Qulbix?

Care to give a little more details about the mid drive? What motor are you using? What controller etc? What is the torque at the rear wheel standard gearing? What is motor max torque? And max peak power?

Happy to see Qulbix going mid drive. I wish you the best for sales figures but fear the Chinese might cause some noise at least now when that sur ron seems to be the most commented bike on ES these days.

Very interesting new model !
I like the fact we don't need any tensioner with the swing arm and motor sharing the same axis.
Great to have two pedaling gears (see question below).
The variable regen is a nice touch.

It would be nice to know the following.
1. What is the nominal and peak power of the mid drive motor?
2. I understand it has two pedaling gears, what exact system is used for that (schlumpf drive or other)?
3. What is the exact ratio between crank and rear wheel for each of the two gears?

Form the first answer I got, Motor is rated with nominal power of 3kW, max. power (when battery is fully charged) 12 kW (150A @ 80V)
As for the pedaling gear, it is unclear, I am getting the feeling there is actually only one gear with a high ratio, but I have asked more details.

So clarification on the pedaling system.
There is only one pedaling gear ratio, which is equivalent to having a 75t in the front. Match that whit either 26, 30 or 38T in the back depending on the chosen option, and you get your pedaling ratio.

So pedaling is only there for street pedaling at high speed, nothing else. There is no pedal assist mode anyway.

Hi Guys,
In respect to the ES policy we don't post much here, as it would be branded commercial. So we'll get back to you faster if you send us an email to info(at)qulbix.com or a message to FB channel or Istagram account.

I assume this is because you need to buy the complete bike and not the frame?

This is tempting, I always wanted a mid drive when they finally were built proper. I've been messing with my hybrid car NimH to lithium conversion for over a year now so I haven't been messing with the ebike, this gets my interest.

The only thing is my Q76R hub motor allows me to do everything. I'm not so sure about not having a sine-wave controller, would the max-e even work with this thing properly.
